This applet explores the velocity vector of a parametric curve, and its relationship to the chord r(t+h)-r(t) and the difference quotient.
This applet shows the construction of the inverse of a function, and can be used to explore whether the inverse is a function.
This applet plots and traces a parametric curve, given as a vector function in R2.
This applet plots two parametric curves simultaneously. It can be used to explore whether two particles collide.
This applet aims to demonstrate visually the projection of a vector u onto a vector v.
This applet explores how the rate of change of a composite function y = f(g(x)) depends on the rates of change of both f and g.
